The vector field of the processors exception frame actually contains
both the vector exception number and fault status field bits.
The exception processing code was not correctly masking out the
fault status field bits before switching on the vector number.
The default case was catching the bad check, but we are reporting
the wrong kind of exception in some cases.

CONFIG_M68KFPU_EMU doesn't exist in Kconfig, therefore removing
all references to it from the source. This Flags seems to exist only
on m68k with mmu, and this dead blocks are copy paste.

Commit 5fd29d6ccb ("printk: clean up
handling of log-levels and newlines") changed printk semantics. printk
lines with multiple KERN_<level> prefixes are no longer emitted as
before the patch.
<level> is now included in the output on each additional use.
Remove all uses of multiple KERN_<level>s in formats.

The old method is used when frame pointers are not available.
Also fix formating with CONFIG_KALLSYMS=n which eliminates \n.

In die_if_kernel() start the stack dump at the exception-time SP, not at the
SP with all the saved registers; the stack below exception-time sp contains
only exception-saved values and is already printed in details just before.

If the kernel OOPSed or BUGed then it probably should be considered as
tainted. Thus, all subsequent OOPSes and SysRq dumps will report the
tainted kernel. This saves a lot of time explaining oddities in the
calltraces.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
